The goal of the experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a, chlorophyll b, carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a spectrographometer. When the data was graphed it clearly showed the higher rate of red light absorption over green light. These results along with previous research indicate the importance of red light in photosynthesis and the minor role green light plays.

These wavelengths correspond to the wavelengths of visible light. Overall blue and red light works best, while green in least effective in the photosynthesis process (Nishio, 2000). The wavelengths that a pigment absorbs, absorption spectra, are determined using a spectrophotometer. In order to obtain the photosynthetic pigment’s absorption spectra the pigments are separated using paper chromatography. Paper chromatography is an analytical technique that separates a mixture based on the individual pigment’s size, polarity and solubility (Lewis, 2004). The separation of the mixtures involves a stationary phase (the chromatography paper), which a mobile phase (solvent) moves up through. When the mixtures is applied to the paper and allowed to flow with the mobile phase, the different pigments move at different rates (Campbell, 1996). This means the pigments that absorb the strongest to the stationary phase (the chromatography paper) will move the slowest, while the weakest will move the fastest. The rate of the pigments movement will separate each pigment individually from the mixture (Maitland, 2002). This natural separation shows that each pigment is chemically different and plays different roles in photosynthesis (Maitland, 2002). To analyze the separated pigments a spectrophotometer is used to obtain an absorbance spectrum. This spectrum is a graph that shows a pigment’s light absorption versus wavelengths

The Green Light in The Great Gatsby
The image of the green light in the novel Great Gatsby, by F. Scott
Fitzgerald, is a significant symbol which reflects Gatsby's dream and other
aspects beyond Gatsby's longing. Throughout the novel Fitzgerald uses many
other images or symbols. At first, it may seem very basic, but when the
symbol is closely studied, one may see the deeper meaning found within it.
Fitzgerald uses these symbols to make a point across to the reader…

Abstract
The effects of light intensity and light wavelength on photosynthesis was observed in two different experiments and closer study of different pigments in spinach was observed. For the experiment where the effects of light was observed, it was found that a light intensity of 30 cm, wavelengths of blue and red lights show the greatest photosynthetic activity. The different pigments present is spinach were also observed and it was noted that though chlorophyll is the most abundant in plants…

tree is able to absorb from the soil. The light in the equation comes from the sun. This is able to be absorbed by different pigments in the plants leaf. The pigments are stored in organelles called chloroplasts; these organelles are what is responsible for photosynthesis. There are may different pigments in each leaf. In this experiment we determine what wavelength of light is optimum for energy absorption in a spinach leaf. I believe that the violet light will be optimum because is is a wavelength…

rstanding the Polarity, Light Absorption, and Effectiveness of the Driving Forces Behind Photosynthesis: Pigments
Kathryn Sawyer
Abstract
To understand pigments and their part in the essential process of photosynthesis, we constructed an experiment to discover first-hand the effectiveness of specific pigments found in pimento leaves. These two exercises would specifically focus on the difference in polarities and the different wavelengths at which each pigment absorbs light. The ultimate source of…

within the red light district (qtd. In Cruz). And, she is right. Being able to “rent” women allows men to feel as if they are in possession of the workers. Many times, feelings of possession can lead to sexual harassment toward women on, and off, the district by tourist feeling as though they are entitled to a women’s body.
That being said, prostitution in Amsterdam is much different than prostitution anywhere else in the world. Being able to understand what a sex worker on the red light district…

Are Red Light Cameras the Answer?
The automobile’s invention revolutionized the American transportation system. It allowed people to move themselves and cargo from city-to-city and state-to-state in a much faster and efficient manner. Its numbers increased as it gained popularity and became affordable. This led to the development of road networks both within and between cities. Problems arose in the areas where roads intersected each other; accidents occurred at these intersections due to the…

purpose of this lab is to demonstrate how color affects heating by absorption of light.
Background Information
The electromagnetic spectrum is the range of wavelengths over which electromagnetic radiation extends (Merriam-Webster Dictionary). The visible part of the spectrum is light and we can see colors from blue to red. On the left side of the spectrum is blue where the wavelength is shorter. On the right side of the spectrum is red where the wavelength is much longer than the blue end. These wavelengths…

you blind? The light is green for Christ's sake!"
I hesitated, but then the taunting red light flashed into my eyes and I felt my foot hit the floor of the car. As I sped away through the red light I glanced in the rearview mirror to see the driver’s face in the car behind me twist into utter disbelief as he and his car remained stationary.
Once again, nothing happened. I didn’t get hit. I run red lights all the time and nothing ever happens, but the one time she runs a red light she dies. One careless…

Great American Dream. The novel starts and ends with a reference to the green light at the end of the dock, indicating an important symbolism. The first time Nick catches sight of Jay Gatsby, Gatsby “stretched his arms towards the dark water […] [Nick] distinguished nothing except a single green light […] that might have been at the end of a dock.” (Fitzgerald 2000:25). Fitzgerald ends the novel by again referring to the “green light at the end of Daisy’s dock.” (171).
The protagonist of the novel…
